Figure 22 is a Vertical section through the sign illustrated in Figure2l showing the arrangement of reflector supports thereupon.

The sign A, illustrated in Figures l through '1 of the drawings,comprises a rectangular frame I0 including spaced parallel horizontallyextending T-bars II and I2 and vertically extending connecting strips orelements I3 and I4. As best illustrated in Figures 2 and 3 of thedrawings the series of .reflector units supports B are mounted onvertical axes between the upper and lower frame elements II and I2. Theelements B are mounted on a single shaft I5 extending vertically throughthe element, or may be mounted on aligned stub shafts projecting fromthe ends of each supporting unit. A ball bearing i6 encirclestheupwardly projecting shaft portion I5 and rotatably supports this shaftportion in the frame element II. A channel bearing I1 rotatably supportsthe lower projecting shaft end I6 upon the transverse frame element I2.Collars I9 and 20 respectively are provided adjacent the bearings I6 andI1 lso as to hold the supporting elements B from vertical movement.

The worm wheel 2I is provided on the lower projecting shaft portion I5and is arranged for engagement with a worm gear 22 mounted on atransversely extending shaft 23. The shaft 23 is supported in suitablebearings 24 and is rotated by any desired means, such as by the motor25. Upon rotation of the motor 25 the supporting units B may be causedto rotate in unison through any desired degree of rotation.

Each of the reflector element supporting units B are constructed as bestillustrated in Figures 4 and 5 of the drawings. The rear surface 26 ofeach supporting element B is flat from side to side. Projectingforwardly from the rear flat surface I provide a pair of converginginclined supporting surfaces 21 and 28 which are connected by a fiatface 30 substantially parallel to the flat rear surface 26. A similarsubstantially parallel flat surface 3I is provided between the inclinedsurface 29 and the adjacent edge of the supporting unit. The twoparallel surfaces 30 and 3| are arranged to support substantiallyparallelly arranged reflector units, while the surfaces 21 and 29 may beviewed one from one side of a line bisecting a sign and normal thereto,and the other on the other side of this line.

In order to support readily changeable reflector elements I provide ears32 extending from the upper and lower ends of the supporting units Badjacent each surface thereof. In other words, a pair of opposed ears 32are provided at opposite ends of the surface 21. A second pair of earsis provided at opposite ends of the surface 29. Similar pairs of ears 32are provided at opposite ends of the surfaces 3E) and 3|. These pairs ofears 32 are arranged to pivotally support a channel 33 having alignedstub shafts 34 projecting from opposite ends thereof. Each channel 33 isprovided with a base 38 and inwardly tapering side walls 35 so arrangedas to retain a wedge shaped body slidably positioned in the same.

Each of the reector elements 36 is provided with a wedge shapedsupporting body 31 secured to the rear surface thereof. This wedgeshaped body 31 is arranged to slide vertically in the channel 33. Thevarious reflector elements 36 are held in adjusted relation by means ofa clamping bar 39 mounted within the channel 33 rearwardly of the wedgeshaped bodies 31. Set screws, such as 4l), extend through the base 36 ofthe channel 33 and press against the bar 39, thus clamping this bar 39against the base of the Wedge shaped bodies 31, thus wedging thesebodies in the channel 33. Thus the reflector elements 36 may be held inany desired adjusted relation by means of the clamping bar 39.

From an examination of Figure 1 of the drawings it will be obvious thatthe sign is to be arranged so that all of the reflecting elements oncorresponding surfaces of the supporting units will be visible from apredetermined location. For example, if the sign is viewed from thepoint 4I, illustrated in Figure '7 of the drawings, -it is desirablethat all of the reectors 36, supported on the surfaces 3d and 3| of thesupporting units be positioned at right angles to a line of vision fromthe point di. This arrangement may be accomplished by adjusting theangular relation of the channels 33 with respect to the surfacesadjacent which they are mounted. For example, in order to adjust theangularity of the channel 33 mounted on the surface 3i), pairs ofadjusting bolts 42 and 43 are arranged in vertically spaced relationthroughout the height of the 4.angular relationship with respectito.tneisurfaee i 3i! so that-.the -reflectorfunits will befdirectly=-=at.right angles to a linef'fdraWnirom the pointAL .In order to `adjust the.channels 53 in one direc- .tionthe bolts its :are loosened andithebcltsfdz .lare tightened. Similarly :to .adjust thefchannels 'inopposite ,direction the :bolts-.ll 2 are loosened-.and the bolts 43 aretightened. Similar adjusting boltsare provided foreachhannel fissoithatthe position `of all ofthe various channels imrytbe regulated.

lnlignretlof thedrawingsl vdisclose a modiiied form of ,construction in.which the support- ...insnnitsiD .are provided with a multiplicity. ofSUPDQIftng @Surfaces S0 .that more than three --relector supporting.channels maybe supported thereby. In the construction shown in Figure 11of the drawings the supporting units D are provided with a flat rearsurface 14 and a curved or multi-faced forwardV surface 15. Five sets ofsupporting brackets or tongues 18 are provided, each of which support achannel 33, identical to that previously illustrated. Each of thechannels 33 is arranged to support reflecting elements 36 which arecapable of reflecting light to a person standing in predeterminedrelation relative to the sign E, as illustrated in Figure 12.

It will be noted that a person standing at the point 11 in Figure 12will see light reflected from the reflector elements 36 mounted at oneextreme side of each supporting unit D. A person standing at the point19 will see light reflected from the reflector elements mounted in thenext adjacent channel. A person standingdirectly forwardly of the signat the point 80 will see light reflected from the centrally mountedreflector elements 36. Persons standing at the points 8| and 82 will seelight reflected respectively from the remaining two sets of thereflecting elements. Thus to a person moving past the sign and viewingthe same from various angles with relation thereto, they will see whatmight amount to an animated sign and as the various displays showsomewhat similar figures in slightly different positions, an effectsimilar to that of a moving picture may be obtained. The reflectingelements may be illuminated either by the lights of passing vehicles orby fixed spot lights or floodlights, such as the lights 83 arranged toilluminate each set of reflector elements.

The reflector elements are preferably directional so that only onedisplay will be seen at a time by a person viewing the same. In certainconstructions and more particularly in those constructions in whichseveral series of angularly arranged rows of reflector buttons areprovided in close proximity, it is sometimes desirable to provideshields encircling the reflector elements and projecting therefrom so asto render the reflector elements definitely directional. These shieldsmay or may not be used.

In Figure 10 of the drawings I disclose a construction very similar tothe construction shown in Figure 8 of the drawings. The supportingelements F, illustrated in Figure 10 of the drawings, are shapedsimilarly to the supporting elements C. These supporting elements Finclude a flat front surface 84 and opposed inclined surfaces 85 and 86.Channels are supported on the surfaces 85 and 86 in any suitable way soas to support reflector elements such as 36. However, the front surface84 is merely painted with a suitable display so that in daylight anadvertising sign is provided without reversing the position of thevarious supporting elements. In other words, the construction shown inFigure l is similar to that shown in Figure 8, with the exception thatthe reflector elements and the supporting channels are omitted on thefront surfaces S, and a painted or decorated display is providedthereupon, visible in daylight hours.

In Figure 13 of the drawings, I disclose another modified form ofreflector supporting element, illustrated in general by the letter G.These supporting elements G are in the form of hexagonal posts 81provided with shafts 89 projecting therefrom so that the supportingelements may be rotatably supported in a manner similar to the method ofsupporting the units B. Six channels 90, similar or identical to thechannels 33, are angularly spaced about the posts 81 and are securedthereto. Each of these channels 90 support reflecting elements 9|similar or identical to the reflecting elements 36. This light will bereflected from six different angles with respect to the axis of thesupporting units G.

This type of construction is capable of numerous uses. In the rst place,a series of supporting units G of the type illustrated, may be mountedin a sign which may be seen from both sides. Thus the sign may bemounted in the parkway between two parallel highways, or may be mountedat right angles to a highway for vision from opposite directions. Thesupporting units may either be stationary in their position, or mayrotate in unison to provide an everchanging display to a person viewingthe same.

Where a sign is so situated as to be visible from both sides lightshield means may be provided between the individual supporting units andthe reflector elements. For example, the spaces between the individualunits may be closed by a flexible flap secured to each supporting unitto extend over the opening between this unit and the next adjacent unit.

In Fig-ures 14 and 15 of the drawings I disclose diagrammatically a signformed of a series of individual reflector supports rotatably mounted insuperimposed relation. Figure 14 discloses a series of laterally spacedreflector supports H, each of which is mounted upon a shaft 92. A seriesof the reflector supports H are mounted on each shaft 92, one aboveanother. The construction shown in Figures 14 and 15 is identical withthe exception that the reflector supports H in Figure 15 are instaggered relationship so that the shafts 92 may be horizontallysomewhat closer together than in Figure 14. As a result the reflectorelements of Figure 15 are Vconsiderably closer together than in Figure14.

The reflector elements H may be of the type illustrated in Figure 16 ofthe drawings. This figure illustrates a spherical body 93 having aseries of angularly spaced reflecting elements 94 mounted centrallyabout the same, each reflector 94 being substantially perpendicular tothe radius of the sphere. The reflectors 94 are also perpendicular to aplane through the axis of the supporting shaft 92.

A second series of reflector elements 95 are provided above thereflector units 94, as best illustrated in Figure 16, so as to reflectlight in an upwardly direction. Similar reflecting surfaces 96 areprovided in the lower portion of the spherical body 93 to reflect lightin a downwardly direction. Thus the sign illustrated in Figures 14 and15 will be visible from a level somewhat above the level of the sign, aswell as from a level somewhat below the level of the sign. Such a signwould be useful opposite a building where the sign might be viewed fromabove or below its level, or might well be used on the wall of a hotellobby, or the like, where it could be viewed from a balcony, as well asfrom a level below the level of the sign.

The signs shown in Figures 14 and 15 could likewise be made up of theunits I, illustrated in Figure 17 of the drawings. This construction hasa multi-sided body 98 having a vertical axis. In the construction shownthe body 98 is a ve sided figure. At the top of the body 98 appears atruncated pyramid 91. A similar truncated pyramid 99 is provided at thelower end of the body 98. The connected bodies 98, 91, and 99 may berotatably mounted upon a shaft |09. Re-

A series of reileotor surfaces|09 are provided on the cylindrical surface ofthperpendicular'tdof-vision IIII from a point Vingelements ISS are ad centreflecting elements I 5. An additional v isior'ivII3 f m apoint I-IlI.yile'cting su fa s I I 2a 15 tioned between adjacent reflecting-siirfa'ces Sinilarly the enrifesurfac of' the siga-J 'may be coveredwith l ertain of the rereecti'ng elements, alternate reiiecting elementsf' of which direct light'towardone point of vision, while the'rein'aining reieting elements direct light to`wardthe second 'pointofvision. Thus asv the si 'gn'l rotats ra constantly changing diseplay'isfpijovided toa personviewing the same.

l `In Figures `1'9faid V20 of the drawings I disclosev a modifiedforinof construction which differssoniewhat fronrpreviously describedconstructions. In thesign illnstratedin Figures 1 9 and-2)A ofi vthedrawings a sign board Ypanel IISl isprovided having an opening;II6therethrough. A

sries of pairsof shafts III and I I9 are mounted'v in any suitableniannerrearwardly of vthe open-- ings IIS. The shafts II'I-arezpositioned relatively near therearsurface of the signv panel I I5,while the shafts IIS are spaced rearwardly from the :shafts II'I.Endless belts or chainsIZY are sup- -ported by rollersor pulleysj-IZ-Iand `|22 on the shafts III and II-9,1respective1y,fand lby rotation,ofthe shafts" the belts may be made to travel {endlessly between thepulleys in; av manner be- ;1ieved obvious from anuexamination of Figure20 l of thedrawings.

Mounted in spaced relation upon each of the belts- Ii', Iprovide'reector elements I2-3 which :,are successivelydisplayedvth-rough the openings I I6 of th'e sign. The reector unitsI-23 are prefi-erably supportedintermediate their ends to the endlessbelt" IZIIrin order that-the reflector units may maintain properrelationship to the sign iopening H6 as they' travel over the pulleysVor rollers I2I. In other words, the reiiector units pulleys I 2I andwhen" Thus fthe flat rear sul'- evv each ofwhich are i Y geeseefgretingSurfaces.; I"I 2 are, provided perpendicular to the lines of the SignDal II5'W-he` in h' position vof the belts. Y

Each reflector element |23 is provided with three angular-ly arrangedfaces I25'; I2@y and I2`I. The reflecting surfaces |26' are clearlyvisible to a person standing directly in -front of the sign and reflectlight directly back at a person standing in rfront ofthe sign; Thereecting surfaces 25 -re'ect light back to a person standing angularlyto one side of thes'ig and in front of the same showing a different orseparate display from that displayed on the frontY surfaces |25. Theremaining angular surfaces I 21 are visible to a person standinginfrontof the sign and to the other side thereof. Thus three separatedisplaysare visible fron differentV angles with reu spect to the signpanel II5.

As each of the reilector elements |23 assumes a vertical plane behindthe display panell I I5 and visible through the opening IIB therein, adifferent display is created; Thus each of the reflector elements I23 isprovided with three separate reflector faces, and as in the formillustrated the belts IZt are each provided with twelve separatereflector elements which successively movey into positionin front of thesign, the sign is capable of displaying thirty-six diierent displays,twelve of which are visible from directly in front of the sign andtwelve of which are visible fromv either l side of the front of thesign. Theb'eltsfmay travel continuously andy without stopping or maymove intermittently, .the belt stopping which each display element is inposition to be viewed through the signopening I I6.

In Figures 21 and 221 disclose another modified form of constructionsomewhat similar to that shown in 1i'lig`ure`s"19 and 20.l The sign L isprovided withv aisign'panell 29 having an opening E30 therethroughthrough which normally vertically'mounted belts ISI are visible. As bestillustratedinFigure 22 the vbelts I3! are inountedontransvers'ely'ext'ending shafts I32 and IBG and rotate about pulleys|33 and E34 mounted on these shafts,t respectively. Rei'ector elementsI35; similarto the reflector elements |23, shown in connection with thesign-K are provided on the belts I 3I. These -reiiector elements IE5 arecentrally connected tothe belt I3.I so that they may travel over theplleys I33 and It without ilexing.

A relatively sinall'nuinber of the reilector elements I3'5 are visiblethrough the opening IE6 at a time. A series o'f'suc'cessiv'eillustrations vmay be izwnrovide'd visible through an opening It or acontinuous sign may be prbvided, the wording on the sign travelingdownwardly or upwardly in order to sncc'essively display all of thereflector elements in unison.

I t 'will besee'n that with-my sign construction a series ofillustrations' 'inlay be provided withoutA moving any of the partstheref,`and` similarly a successiveV series of's'igns may be displayedvisible from different anglesfor successively brought into view of aperson standing in a certain'spot. Reflector elements are embodied inthevai'ous sign constructions, each-'element-being so constructed as tobe'substantially directional, sothat only one display of the sign may be'seenfrom any point at one time.

`In accordance with thev patent statutes, I have described theprinciples of the construction and operation `of rny signyandjwhileI-have endeavored to set forth thebest embodiments thereof, I desire tohave it understood that obvious changesy may be made 'within' the scopeof the following claims without departing from the spirit of myinvention.
